Abstract

PURPOSE:To economically and simultaneously receive radio waves coming bidirectionally by containing the another antenna having a small-sized receiving surface inside one antenna having a large-size receiving surface. CONSTITUTION:Inside one antenna (master antenna) 1 having linear directivity to receive a weak radio wave, a small-sized antenna (slave antenna) 2 having a different directivity to receive a strong radio wave is contained. In such a state, ratio waves coming bidirectionally are received simultaneously, and the radio waves are supplied to a receiver by one piece of cable. Also, in the case there is a variation in the direction of the two directions, the small-sized antenna 2 is movable so as to correspond thereto. In such a way, radio waves coming bidirectionally are received simultaneously by one antenna, and both the equipment and the occupied area can be reduced to the minimum.

Receiving simultaneously with two antennas requires minimum equipment and area, and if the direction of the radio waves changes or the strength of the radio waves changes, secure the area of the antenna according to the strength of each radio wave. Therefore, a child antenna corresponding to stronger radio waves is built inside a main antenna corresponding to weaker radio waves, and radio waves coming from two directions can be received simultaneously in the most economical way.
